The release includes specific conductance data from a series of sodium chloride tracer slug injection experiments conducted on June 11, 2025. These time-series datasets capture tracer breakthrough curves across sequential measurement locations within subdivided upper and lower channel sections, separated by a large plunge pool, to characterize reach-scale streamflow and quantify losses and gains. Additionally, the release serves passive seismic horizontal-to-vertical spectral ratio (HVSR) data, providing estimates of unconsolidated sediment thickness for 14 locations where ambient vibration processing criteria were met.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P133HGRG", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.68b9ac5cd4be021c5e4c97a7.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_68b9ac5cd4be021c5e4c97a7", "keyword": ["Hydrogeology", "Luzerne County", "Nanticoke Creek", "Pennsylvania", "USGS:68b9ac5cd4be021c5e4c97a7", "Water Resources", "environment", "geophysics", "geoscientificInformation", "groundwater", "groundwater quality", "inlandWaters", "tracer", "water quality"], "modified": "2026-06-24T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-75.96743, 41.18275, -75.95123, 41.20022", "theme": ["geospatial"], "title": "Salt Tracer and Passive Seismic Horizontal to Vertical Spectral Ratio Data from Nanticoke Creek, Pennsylvania (2024-2025)"}
